Knox Martin (born February 12, 1923 in Barranquilla, Colombia) is the son of the aviator, painter, and poet William Knox Martin, the first man to fly over the Andes mountains.

After serving in World War II, Knox Martin attended the Art Students League of New York on the G.I. Bill from 1946-1950, where he studied with Harry Sternberg, Vaclav Vytlacil, Will Barnet, and Morris Kantor.

In 1954, Knox Martin's friend Franz Kline placed a painting of his in the Stable Gallery Annual. Charles Egan of the renowned Charles Egan Gallery saw Knox Martin's painting at the Stable Gallery and asked Martin to show his work in a one-man show for the tenth anniversary of the Egan Gallery.

Since then, Knox Martin has been a celebrated painter, sculptor and muralist. Knox Martin has an extensive exhibition record and his work is in museum, corporate and private collections worldwide. His two best-known murals in NYC are Venus and Woman with Bicycle. Knox Martin has been the recipient of many grants and awards, most recently the Benjamin West Clinedinst Memorial Medal, awarded by the Artists’ Fellowship “for the achievement of exceptional artistic merit.”

Knox Martin has also led a distinguished career teaching art. He taught at Yale Graduate School of the Arts, New York University, University of Minnesota, International School of Art in Umbria, Italy, and currently gives Master classes at the Art Students League of New York.

Knox Martin lives and works in New York City.

"Art is at its cutting edge out of a specific lineage - the creation of reality. The subject matter of what I do is Art." - Knox Martin

After Knox had given a talk on children's art (Olivia's paintings and drawings) age 6, on paper and blackboard, to Cy Twombly, Bob and Susan Rauchenberg -- Cy jumped up and said, "That's what I am going to do for the rest of my life!" He did.
